| Outline of Final Research Achievements |
In this study, we attempted to measure and analyze brain activity during vertical jump with trampoline using a mobile electroencephalograph in order to clarify unusual brain activity during sports activities. Electroencephalogram (EEG) and accelerometer were simultaneously measured. The time of separation, top arrival, and landing in the trampoline jump was identified from the data of the accelerometer. Then the time frequency analysis of the EEG data was carried out.
All subjects reported a change in subjective time perception in which the time of the downward phase was longer than the time of the upward phase in trampoline jumping.From the result of the EEG analysis, the possibility in which this change of the subjective perception was related to the increase in the sensorimotor rhythm component observed in reaching the top was indicated.

| Academic Significance and Societal Importance of the Research Achievements |
ダイナミックなスポーツ中の脳活動計測・解析を試みた研究である。トランポリンの垂直ジャンプにおいて、下降局面の方が上昇局面よりも主観的な時間知覚が長いことに着目してそのメカニズムをモバイル脳波計を用いた脳機能計測・解析から明らかにしようとした。
こうした試みは、スポーツという非日常な体験での知覚の変容や脳の働きを明らかにすることでスポーツの理解を深め、国民のスポーツへの興味関心を高めることが期待される。
